BACTEREMIC URINARY-INFECTION IN MEN - COM PARATIVE-STUDY WITH BACTEREMIC PYELONEPHRITIS IN WOMEN

OBJECTIVE: TO compare the clinic and microbiologic caracteristics of t he extrahospitalary bacteremic urinary infections (EBUI) between men a nd women assisted in a 200 bed community hospital. PATIENTS AND METHOD S: A prospective study of the EBUI diagnosed in our hospital from Janu ary 1991 to April 1994 was carried out. Quantitative variables were ev aluated with t Student analysis, chi(2) was used for the comparation o f proportions. The logistic regression step-by-step model was used in order to find out which variables influenced that the microorganism ca using EBUI was Escherichia coli. RESULTS: 107 episodies of EBUI were r ecorded, 39 men and 68 women, with the same microorganism in blood and urine. Significative diferences in age (70 +/- 17 years in men, 58 +/ - 24 years in women); the presence of urinary tract alterations (49% m en vs 12% women) and in the presence of indwelling urinary catheter (2 6% men vs 3% female) were found. E. coli was responsible in a major pr oportion (p = 0.03) of the EBUI in women that in men, but only age > 6 5 was selected as explaining variable with the logistic regression mod el. CONCLUSIONS: The EBUI appears in old men with urinary tract altera tions and/or manipulations, clearly diferent from the EBUI in women. A ge greater than 65 years is the only predisponent factor of EBUI in me n by bacteria other than E. coli.
